"When a user clicks on a button, all \<p> elements will be hidden:" - here the "\<p>" is taken as html tag due to which text is moving to next line. The intention of author is to say that all paragraph (\<p>) tags will be hidden. The "\<p>" itself is not showing as it's considered an HTML tag. I have added an escape character in front.

## jQuery
|
|
|
|
|
|
|
|
jQuery is the most widely-used JavaScript library, and is used in more than half of all major websites.
|
|
|
|
jQuery makes web development easier to use by providing a number of 'helper' functions. These help developers to quickly write DOM (Document Object Model) interactions without needing to manually write as much JavaScript themselves.
|
|
|
|
jQuery adds a global variable with all of the libraries methods attached. The naming convention is to have this global variable as <code>$</code>. by typing in <code>$.</code> you have all the jQuery methods at your disposal.
|
|
|
|
## Example
|
|
|
|
When a user clicks on a button, all \<p> elements will be hidden:
|
|
|
|
```javascript
|
|
$(document).ready(function(){
|
|
$("button").click(function(){
|
|
$("p").hide();
|
|
});
|
|
});
|
|
```
